numpy as package

[pintman]

Hi!

Yesterday I needed a numpy dependency on a pizero (namely for scroll-phat-hd). The process took about 2hrs to compile on picore. Maybe a binary package for numpy would be a good decision.

Now you've compiled numpy, it would be great if you could submit it 

[pintman]

I don't know how this can be done. Is there a tutorial or wiki article I can follow?

Hi pintman
As a matter of fact, there is:
http://wiki.tinycorelinux.net/wiki:creating_extensions

[pintman]

Thanks for the hint. I will have a look into it and check if I can do anything.

[pintman]

I sent a submission. Hopefully I did all right.

As I found out, there is a repository of python packages called piwheels that contains packages compiled for arm. It should be a better solution to use this repository instead.

[pintman]

Another update: The numpy version in piwheels has a dependency to fortran a library called libatlas - which is available on the raspberry pi but not in picore. Therefore it cannot be installed via piwheels. However, other binary packages might be usabale.

Even if it takes longer, it will still be better to compile natively

[pintman]

piwheels packages will be compiled on a Raspberry Pi 3.

Natively meaning the software environment in this context, not hw vs cross.

So can the ArmV8/Aarch64 version of PiCore be compiled on the 32bit version?
